Va’yishma Adonai et kolaynu, And Adonai heard our voice: The proof text used in the Haggadah suggests that it was not just their prayer but God’s remembrance of His covenant that led Him to redeem the people. We have yet another verse later in Exodus which explicitly says this, “I heard the groaning of the people of Israel and I remembered My covenant.” So why doesn’t the Maggid use this verse as the proof text to make this point instead of the one quoted in the Haggadah? There are two reasons: first, because the verse that is quoted in the Haggadah appears first in the Torah; and second, because Exodus 2:24 explicitly mentions that this is the covenant of Abraham and Isaac.
